sANb-BLAs MECHANISM Be it lnaown that I, FREDERICK K. ViAL', a citizen of the United States, resi in La Grange, count of Cook, and State of ois, have invent certain new and usefulImrovements in Sand-Blast Mechanisms, of

My invention re ates to that class of sandblast mechanisms having a suitable receptacle for receiving the article to be operated upon and provided with means for introduc ing a plurality of currents or blasts so that the strike opposite portions or sides of the art cle to-be operated upon. I

The principal object of this invention is to rovide a sim 1e, economical, and efficient sand-blast mec anism adapted to be used for as car-wheels and t ike. A further object is to provide a sand-blast mechanism adapted to-subject the article to be operatedupon to a plurality of currents or blasts and sand, so as to enablethe-arti; cle operated upon to be'cleaned on opposite sides without. thenecessity of removing it from the blast-boxer reversing it laterally during the process of being-cleaned.

Other and further obj ects-of the invention will appear from an examination of the drawingsand the following description and The invention consists in a sand-blast mechanism having a suitable receptacle or blast-box for conta the article to be operated-rupon androvi ed with means forintroducirig;aiplura it of currents or blasts of air con-taming sand mto-the blast-box at different points and on opposite sides of such article, whereby the article may be cleaned f on both sides withoutbeing'removed and" laterally reversed.

It consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed;

These perforated supporting members form the sockets of be and-socket joints,an d each nozzle is provided V with a ball member 3, which is seated "in such i an end tip 4, secured thereto b socket members. An air-tight joint is thus formedv between the nozzles or blast-pipes and their supports. i

l. The bran'chpipes may be made of flexible material, and the nozzles thus permit the dijjusting the nozzles to point in the desiredidirection. The nozzles are each provided with means of a se rew 5,-such tips having aring or enlarged discharge-passages 6, which permit the blastto spread to the desired extent as it blast-box,

comes into contact with the wheelor other articleto be operated-up'on.

The blast mechanism here shown is particularly adapted to'be used for cleaning car: wheels. l [t 1s desirable. to provide suitable means for introducing the wheels into .the

char them therefrom, and-also suitable means for kee the wheels in rotation while they are eingo erated'upon. To accomplish this, a plura ity'ofconicalsupportrug-rolls 7 having peripheral grooves 8 for recei the flanges of the car-wheels to be operate upon, are mounted in the blast-box with their axial centers arra ed transversely of such box orrece tacle. hese wheels are -mounted upon sha s 9 and 10, which are rotatably mounted in bearings 11 and 12. The

10 with a sprocket 14, andla sprockets chain 15 is mounted utpon. and connects such shaft 9 is provided with a sprocket 13 and the shaft sprocket wheels, an

I thereby the shafts, so that they rotate together. A dri g spzocket-lwheel 16 is-also -mounted'uponthe s ft 9 and is adapted be connected with a suitable source of power in any ordinary and well-known manner.

I a

A pair of track-rails 21 extend into: the receiving side of thedalast-box in suchposition that their inner ends are on opposite sides of the peripheral groove of the adjacent supporting-roll and their upplr bearing-surfaces preferably almost on t slightly below the upper supporting-surface of the adjacent grooved roll. These rails. have a space therebetween .of substantially the same Width as the groove in th'adjacent roll and are adapted to permit the a'nges 22 of the car-wheels 23 to be olperatedupon to ass between such rails and e guided there- 7 y into the eripheral grooves of the supporting-roll's. imil ar tracks 24 extend from the olpposite supporting-roll outward through t e discharge side of the blastrbox beneath the vertically-movable door and are adapted to guide the car-wheel, with its-flange ortion, between suchrails as it is discharged rom the blast-box after being treated. WV'hile the car-wheel is in the blast-bOxit rests upon the supporting-rolls 7, already described, withe same 'plane or -V its flange in. theperipheral grooves in such rolls. By keeping the rolls in rotation while introduced the ,wheel may be kept constantly in rotation and subjected to the action of the blast at all points and on opposite sides simultaneously.

. 11 order to provide suitable means for discharging the wheel fromthe blast-box, Va

rock shaft 25 is mounted transversely of such box in suitable bearings in the'brackets 17, and 19, already described, and an oper-' ating-lever 26 issecured-to such rock-shaft. I

The rock-shaft is provided with a curved crank-arm 27, having its outer swinging end 28 intermediate the en'd-of-one of the rails 21 and the adjacent supporting-roll. The rockshaft is mounted intermediate the support- 4 and 6,, and subing-rolls, as shown in Figs.

the axial center stantially, on a plane with thereof, so that when the operating-lever is moved in the direction to raise the swinging,

end of the crankarm the car-wheel wil be discharged from the rolls onto the dischar ing-rails. An desired number of whee 8 may be intro need and discharged consecuin a similanmanner by simply raising in manually and out by means of the rock-shaft and lever mechanism. Q

To permit the doors to be readily raised and lowered, 'a counterweight 29 is connected therewith by means of the flexible elements :30, which Inay be in the form of metallic cords mounted upon sheave-pulleys '31, 32,.

33, and 34, sup orted above the doors upon a suitable fixed ame portion 35 bymeans of brackets 36. The lower ends of these flexible elements are provided with loops 37, by means of .which they are attached per ends of the vertically-movable doors,

to the up- 1 reach of-the operator.

V I ,..aa9,a42 y and the opposite ends are connected with the counterweight above described by means of a link 38 and an eyebolt or link 39. An operat' -cord 401s attached to the .lower end of the'eyebolt or link and is adapted to extend to anyfldesired point within convenient compressed-air p pe 41 communicates with-the converging ends of the sand-:blast pipes t and with a source of compressed air,

such pipe being provided with a controllingv valve 42, ;having operating-levers-v43, by

of which the air-passage may "be pressure may be thus admitted to the blastpipes to form blasts which will force the sand into contact with the wheel or other article to be operated upon.

An outletipe 44 leads from the upper portion of the last-box or operating-chamber downward to a dump box or receptacle 45,

having a dischargeopening. This receptacle is adapted to receive the heavier partitling chamber until the dust is permitted to settlein the resides t ereof, so as to ceptacle. An' air-discharge pipe 50 is provided, in whichis mounted a suction-fan 51 for forcing the air from the settling-charnber after the dust has settled. The chamber or receptacle 4'7 is provided with a hopper-bottom portion 52, the inclined portions of which extend downward and toward the center of the ho per at-an incline from the opposite conve the dust to the discharge-opening the bottom portion or chute 53. Apipe 54.1eads from the bottom of a sand receiving and discharge box 55 at the bottom of the blast-box or operatingchamber and into the discharge-pipe 46, so that sand is forced from such box into the discharge-pipe and from such ipe'into the settling chamber or. receptacle above described. When the exhaust-air with the sand and other particles contained therein reaches this chamber from the blast-box, the heavier particles of sand are fit to be used over again, and the lighter particles in the form of dust, while not of any further use, should be permitted to settle before leaving the chamber. This protects the health of the operator. The heavier particles of sand come in contact with the first upwardly-extending baflie 49 and are discharged through a pi e 56 into a se arating box or chute 57, having an incline screen 58 and beneath such screen another similarly-inclined screen -64, which closed, as desired. Air under receptacle 63 and of finer mesh. The screen 59 extends over a discharging-hopper portion 60 and the screen '58 over the hopper portion 61-, the box being provided with an inclined discharge 62 beyondsuch main holpper Sprtion for discharging into a receptac e 63. too coa rse to pass through either screen. The main hopper portion 61 has a discharge-chute leads to the initial sand receiving and feeding hoppere, already described. By

this 'Ineans-it will be seen that the sand or other material-which will notpass through the screen .58 is finally djschargedinto the that the material which will pass through such screen, but not through the screen 59,- is emptied into the initial sand receiving and feeding hopper to be used over again, while the particles of material which are so fine as to pass through the screen 59 are discharged through a chute or pipe 65 onto a suitable receptacle or dump for receiving the waste material. v
